IMPROVED SPRING BED-BOTTOM.

The Schedule referred to in these Letters Patent and making part of theBama.

` marked thereon, forming a part of this specification.

Figure l is a plan view of my invention.

Figure 2 is a view. of the bottom ofthe bed.

Figure 3 is a sectional view of the tightening-apparatus,7 situated atthe foot of the bed.

Figure 4 is a-detached view of one of the sockets for the ends ofwhat isknown herein as the head- Figure 5 is a detached view of the socket forone of the ends of the-foot-piece.

Figure 6 is a detached view of the socket for the other of the ends ofthe foot-piece.7

The letters a a a designate the three sections of which the bed iscomposed, which sections are made of stout canvas, or of some equivalenttherefor.

1f the Whole bed were made in onei piece, when two persons Inade use ofit, they would both roll into the middle together, while, by making thebed in sections, I avoid this difficulty altogether.

The sections are laced somewhat loosely together by strings runningthrough eyelet-holes.

lAt the head of the bed is a stout bar, of wood, b, called a head-pieceherein, each end'of which fits down into the sockets c, shown in tig. 4,which socket-s are iXed to the inside of the two side pieces,d and d, ofthe bed.

These" sockets can just as well be made into the side pieces, but Ithink a metal socket, screwed to the side, is preferable.

It will be readily understood that the head-piece b is removable atpleasure from the sockets.

The sections a are attached to the head-piece b,4 each by means of twoshort bars of metal, made into a ring at one end, which is stoutlyfastened to one end of the section. Each of these bars runs into thehead-piece, and through a spiral spring, or its equivalent,.and isattached to the back of the spring, which spring is contained in aproper socket in the headpiece, and the other end of the spring fromthat to which said bars is attached, rests against the bottom of thesocket. This arrangement, so far as concerns one ofthe springs, isrepresented at e.

At the foot of the bed, the sections run overthe foot-piece fi, downunder the bed. This foot-piece is a sort of a cam or eccentric, thehearings of which rest in the sockets h and h', and from ther shape of hit will readily be understood that the footpiece,as well as thehead-piece, lis removableat pleasure.

These sockets, la, and h', are screwed to the insides of the side-piecesof the bed, dgl.

The sections come to van end shortly after passing around the c'am i. Tothese ends are attached the strainers 7; k k, which are buckled at theirother ends to the bottoms of thesections, andby means of these strainersany desired tension can be given to the sec# tions.

It is also desirable to tack the sections to the bottom of the cam fi,as by the tacks, o o o o o o, shown, and then when the strainers arebuckled tighter, the action of the cam will also assist in straining thesections.

A. roller and ratchet can be substituted for the cam, but I think thecam preferable.

I claim as my invention- The webbing-bottom, made in sections,` lacedtogether as described, in combination with the strainers k la k, themovable head-piece b, with its sockets, springs, and bars, and the` cami, the whole arranged and constructed as described, for the purpose setforth.
